The numbers of properties and districts in New York State or in any of its 62 counties are not reported by the National Register. Following are approximate tallies of current listings from lists of the specific properties and districts.
^ abThe approximate counts are the best available. There are frequent additions to the listings, and occasional delistings, and the counts here may not be perfectly updated. Also, not counted are most boundary increase listings, which increase the area covered by a historic district and which carry a separate National Register reference number. An exception is Grand Central Terminal Park Avenue Viaduct which is treated here as a separate property, although it was added to the National Register as a boundary increase to the Grand Central Terminal.
